Description

  The present invention relates to a drawing check tool for checking design contents displayed on a design drawing of a building.

In the construction of a building such as a house, the design is performed by displaying the shape, arrangement, specifications, etc. of the building or member on a drawing such as a flat elevation or a floor plan. Then, based on these drawings, specifications, etc., it is determined whether the design contents satisfy various standards such as the Building Standard Law.
When checking the design contents, if the standard to be satisfied for a certain object requires its dimensions and arrangement, etc., determine whether the standard is satisfied by measuring the dimensions and arrangement of the object on the drawing. There was a need to do. Such confirmation work is cumbersome, easy to make mistakes, and requires labor.

Therefore, for example, it has been proposed to use a building ruler as a check tool so that it is possible to easily and quickly determine whether to satisfy the oblique line restriction of the Building Standard Law. (For example, refer to Patent Document 1).
The construction ruler in Patent Document 1 is a transparent or semi-transparent ruler with restriction lines (road oblique line, north oblique line, adjacent oblique line, etc.) for checking various oblique line restrictions, and this ruler in the design drawing. It is possible to determine whether a building or the like in the design drawing does not exceed these limit lines.

On the other hand, in recent years, there has been a tendency to improve design specifications related to crime prevention and disaster prevention, and various laws such as the Building Standards Act and the Housing Quality Assurance Promotion Act have also reviewed various design standards and guidelines related to crime prevention and disaster prevention. It is illustrated. Therefore, it is necessary to check whether the design contents reflect these standards and guidelines as needed. However, the check operation so as not to be overlooked is very complicated and labor-intensive.
However, heretofore, no tool has been proposed for improving the efficiency of checking the standards for crime prevention and disaster prevention. In addition, a ruler with a restriction line such as a so-called drafting rule as in Patent Document 1 is supplied by a manufacturer who manufactures the ruler. It was difficult to obtain quickly. Further, in order to eliminate the complexity of work, it is required that even a large number of check items can be checked with as few tools as possible.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to efficiently check whether the design content displayed in the drawing satisfies various design standards related to crime prevention and disaster prevention. To provide a drawing check tool.

According to the drawing check tool of the present invention, the subject is an auxiliary line for aligning with a reference position on an architectural drawing, and the positional relationship between the check target displayed on the architectural drawing and the reference position is It is solved by displaying a determination figure including a determination line for determining whether or not a design standard related to crime prevention or disaster prevention of a building specified by an architectural drawing is satisfied on the surface of a substantially transparent sheet. .
If comprised in this way, the positional relationship of the determination figure and the check object on drawing can be easily grasped | ascertained only by superimposing the sheet | seat on which the determination figure was displayed on an architectural drawing, and aligning with an auxiliary line. Therefore, it is not necessary to measure the dimensions at each check. In addition, since the reference content is clearly displayed as a determination graphic, there is no mistake that the reference content to be checked is wrong. Therefore, the check work for determining the degree of conformity to the design standards related to crime prevention and disaster prevention is facilitated, and the check accuracy is improved.

In the present invention, the check target includes at least one of a sensor installed in the building, an opening of the building, and an outer shape of the building, and the design standard for the sensor is used as the determination figure. It is preferable that at least one of the determination graphic of FIG. 1, the determination graphic of the design standard related to the opening, and the determination graphic of the design standard related to the outer shape of the building are displayed corresponding to the check target.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. It should be noted that members, arrangements, and the like described below do not limit the present invention, and it goes without saying that various modifications can be made in accordance with the spirit of the present invention.
FIGS. 1-5 shows one Embodiment of the outer wall surface material of this invention, FIG. 1 is explanatory drawing of the determination figure (determination figure B) for determining a performance ruler A and a fire spread line, FIG. FIG. 3 is an explanatory diagram of a determination graphic (determination graphic D) for determining the position of a sensing alarm device, and FIG. 4 is a determination of azimuth and angle. It is explanatory drawing of the determination figure (determination figure E) for doing.

An embodiment in which the drawing check tool of the present invention is applied to a performance ruler A for checking a house design drawing will be described.
As shown in FIG. 1, the performance ruler A is obtained by printing a predetermined determination graphic on a transparent sheet. In this example, for example, an A4-size OHP sheet is used as the transparent sheet, and four determination figures (determination figures B, C, D, and E) are printed on the color printer.
The performance ruler A in FIG. 1 performs a correct check on a reduced drawing obtained by reducing a design drawing (plan view, layout drawing, etc.) created at a scale of 1/50 or 1/100 with a reduction ratio of 70%. It is formed so that it can be. That is, the determination graphic printed on the performance ruler A has a dimensional ratio of 0.02 (1/50) × 0.7 = 0.014 times the size of the check target in the current size building, or 0.01 (1/100) × 0.7 = 0.007 times.

Hereinafter, the determination figures B, C, D, and E will be described.
The determination figure B is created at a ratio applicable to checking a reduced drawing obtained by reducing a design drawing created at a scale of 1/100 with a reduction rate of 70%. This judgment figure B indicates whether or not the outer shape of the building displayed in the plan view, the elevation view, the layout drawing, etc. is at the position (within the fire spread line) where the fire prevention structure should be taken in accordance with the fire prevention regulations of the Building Standard Law. Can be determined.
More specifically, in the fire prevention regulations, for buildings constructed in the semi-fire prevention area, when the distance from the boundary of the adjacent land is within 3 m for the first floor of the building and within 5 m for the second floor, It is stipulated that the back of the eaves must be fireproof. Therefore, these 3 m and 5 m lines are used as fire spread lines.

As shown in FIG. 1, the determination figure B includes grid lines B1a and B1b drawn in a grid pattern, and fire spread lines B2a and B2b drawn on the grid lines B1a and B1b. . The grid lines B1a and B1b are drawn in a grid pattern and alternately arranged in a substantially square area, and the smallest one cell interval (the interval between adjacent grid lines B1a and B1b) is the module of the building. The spacing corresponds to the dimension (910 mm). According to the above-mentioned ratio, 0.007 × 910 = 6.37 mm is an interval of one square. The grid line B1a is drawn with a solid line, and the grid line B1b is drawn with a broken line. At the intersection where the grid line B1a drawn with a solid line intersects vertically and horizontally, a ● mark is attached every time the number of the grid lines B1a becomes the fifth. Therefore, it is easy to read the number of grids.
The fire spread lines B2a and B2b are drawn at positions 3 m and 5 m apart from one end of the grid line B1a as a reference position (reference line B0). “0m”, “3m”, and “5m” are displayed on one end of the reference line B0, the fire spread line B2a, and the fire spread line B2b, respectively, so that they can be identified.

The determination by the determination figure B is performed as follows. First, the performance ruler A is overlaid on a drawing such as a plan view or an elevation view so that the reference line B0 of the determination figure B coincides with the adjacent boundary line on the drawing. And when the outline line of a building exists in the fire spreading line B2a and B2b, it is confirmed whether the specification of the location suits a fire prevention structure. If it conforms, the design standard is satisfied, and if it does not conform, the design standard is not satisfied. That is, the “reference line B0” corresponds to the “auxiliary line” of the present invention, and the “fire spread lines B2a and B2b” correspond to the “determination line” of the present invention.
Note that the grid lines B1a and B1b drawn on the determination figure B can be used to easily measure the module dimensions of each part of the drawing by being used overlapping the drawing. Further, if the above-mentioned minimum one cell is measured as 0.5 module (455 mm), it can be used for a reduced drawing obtained by reducing a design drawing created at a scale of 1/50 with a reduction ratio of 70%. In this case, the interval between the grid lines B1a drawn with a solid line corresponds to the module dimension (910 mm) of the building.

  The determination figure C is created at a ratio applicable to checking a reduced drawing obtained by reducing a design drawing created at a scale of 1/100 with a reduction rate of 70%. With this determination graphic C, it is possible to determine whether or not the opening of the building displayed in the elevation is at a position exceeding 2 m in height, which is a criterion for determining the security category in the Housing Quality Assurance Promotion Law. .

As shown in FIG. 2, the determination figure C includes two horizontal lines C0 and C1 that are substantially parallel, and vertical lines C3 to C6 that are substantially perpendicular to C0 and C1. The distance between the horizontal lines C0 and C1 is a dimension (2000 × 0.007 = 14 mm) corresponding to an actual dimension of 2000 mm. Vertical lines C3 and C6 are drawn connecting the ends of C0 and C1, respectively. The vertical lines C4 and C5 are drawn at positions separated from the vertical lines C3 and C6 by a dimension (900 × 0.007 = 6.3 mm) corresponding to the actual dimension 900 mm.
In addition, inclined lines C7 to C10 having a predetermined gradient with the horizontal lines C0 and C1 are drawn from both ends of the horizontal line C1 and the intersections of the horizontal line C0 and the vertical lines C4 and C5. The slopes of the inclined lines C7 to C10 are 4.5 inch slopes, which correspond to the roof slope of the building.

  As a determination method using the determination graphic C, first, the performance ruler A is superimposed on the elevation so that the horizontal line C0 of the determination graphic C coincides with the ground or balcony floor line. In this state, it is determined whether or not each opening displayed on the elevation is above the horizontal line C1, that is, whether it is at a position higher than 2 m in height, which is a criterion for judging the security division. It should be noted that whether or not the lower end position of the opening is at a position 0.9 m or more away from the line of the lower floor roof or balcony floor is a criterion for judging the b section of the crime prevention section. The vertical lines C3 and C4 and the vertical lines C5 and C6 drawn at intervals corresponding to the actual size 900 mm can be checked.

In addition, by aligning the intersection of the horizontal line C0 and the vertical line C4 or C5 with the eaves on the lower floor and matching the horizontal line C0 with the eaves line, the lower end position of the opening on the upper floor is 2m from the roof slope surface of the lower floor It can be determined by the inclined lines C7 and C8 whether or not the distance is more than 0.9 m and the horizontal distance. Whether the horizontal distance is 0.9 m away from the eaves is determined by the vertical lines C3 and C6.
That is, the “horizontal line C0”, “vertical line C4”, and “vertical line C5” correspond to the “auxiliary line” of the present invention, and the “horizontal line C1”, “vertical line C3”, “vertical line C6”, and “inclined line C7”. Corresponds to the “determination line” of the present invention.
Furthermore, when the determination of the horizontal distance from the lower floor roof eaves is unnecessary, the lower end position of the upper floor opening is adjusted to the lower floor roof slope surface by matching the slope line C9 or C10 with the lower floor roof slope line. It can be determined from the inclined lines C7 and C8 whether or not it is at a position more than 2m in height and 0.9m or more in horizontal distance.
In this case, the “slope line C9” and “slope line C10” correspond to the “auxiliary line” of the present invention, and the “slope line C7” and “slope line C8” correspond to the “determination line” of the present invention. To do.

The determination figure D is created at a ratio applicable to checking a reduced drawing obtained by reducing a design drawing created at a scale of 1/50 with a reduction rate of 70%. This determination figure D is used to determine the interval between the objects displayed on the plan view.
As shown in FIG. 3, the determination figure D is composed of cross-shaped scale lines D1 and D2 and annular lines D3 to D6 centering on the intersection of the scale lines D1 and D2. The scale lines D1 and D2 are graduated at intervals corresponding to the actual size of 100 mm (100 × 0.014 = 1.4 mm). The annular lines D3 to D6 are drawn so that the respective radii have dimensions corresponding to the actual sizes of 300 mm, 600 mm, 900 mm, and 1500 mm.

As a determination method using the determination figure D, first, the performance ruler A is overlaid on a drawing such as a plan view so that the position of the check object displayed on the drawing matches the position of the intersection of the scale lines D1 and D2. Combine. In this state, the interval between the check object and another object is determined depending on whether or not it is located inside the annular lines D3 to D6.
That is, the “scale lines D1, D2” correspond to “auxiliary lines” of the present invention, and the “annular lines D3 to D6” correspond to “determination lines” of the present invention.

Check items based on the determination graphic D include, for example, determination of whether or not the opening is a target of the above-described crime prevention classification. That is, if the intersections of the scale lines D1 and D2 are overlapped on the balcony floor, it is determined whether or not the ring line D5 is subject to the crime prevention division (whether or not the horizontal distance is within 0.9 m). it can.
Further, as a check item for crime prevention, it is necessary to determine whether or not there is a space (width of 0.3 m or more) where a person enters outside the balcony handrail. This is because if there is such a space, it becomes a foothold for intruders. Specifically, if the intersections of the scale lines D1 and D2 are superimposed on the balcony handrail, it can be determined whether or not there is a space that can serve as a scaffold for the intruder by the annular line D3.

  In addition, as a check item for crime prevention / disaster prevention, there is a determination as to whether or not the separation interval of the sensing alarm device satisfies a standard. For example, according to the Fire Service Act, it is obliged to install residential fire alarms to notify the occurrence of smoke or abnormal heat generation in the house. The distance between the center of the alarm device and the wall surface is set to 0.6 m or more, and the distance between the center of the detection alarm device and the air outlet of the air conditioner is set to 1.5 m or more. Therefore, if the intersections of the scale lines D1 and D2 are superimposed on the installation position of the sensing alarm on the plan view, it can be determined whether or not the above-mentioned installation standard is satisfied by the annular lines D4 and D6.

As another check item, there is a determination for obtaining an appropriate installation position of the sensing alarm when there are two or more objects to be separated. For example, when both the air outlet of the air conditioner and the air outlet of the ventilator are in the room, it is necessary to obtain a point at least 1.5 m away from both as the installation position of the detection alarm. For this purpose, the determination figure D is superimposed on the plan view so that the annular line D6 passes over the two separated objects. If it does in this way, the intersection of graduation lines D1 and D2 will become a limit point for installing a sensing alarm device at a distance of 1.5 m or more from two separated objects. The performance ruler A in this example has small holes for marking on the paper surface with a writing tool at the intersections of the scale lines D1 and D2. Therefore, by using this small hole, the limit point can be easily entered on the drawing.
That is, in this case, the “annular line D6” corresponds to the “auxiliary line” of the present invention, and the “scale line D1” and “scale line D2” correspond to the “determination line” of the present invention.

The determination figure E can be used for determination of azimuth and angle, and can be used regardless of the scale of the drawing, the reduction ratio, and the enlargement ratio. As shown in FIG. 4, the determination figure E has the same shape as a so-called full-circle protractor having a scale of 360 degrees, and a scale line E1 of 360 degrees drawn in 1 degree increments, and this scale line. And an annular line E2 centered on the center point of E1.
The scale line E1 has three types of scales, and the scale on the outermost side is attached clockwise, while the scale on the inner side is attached counterclockwise. Yes. Further, the scale on the innermost side is firstly increased from 0 degrees to 90 degrees clockwise, then decreased from 90 degrees to 0 degrees, and again increased from 0 degrees to 90 degrees. The decrease from 0 degrees to 0 degrees is repeated.

Examples of the check item based on the determination figure E include determination of the orientation and angle of the check target in the drawing. The determination figure E is thus provided with the scale line E1 in all directions, and further, the angle indicated by the scale line E1 can be read both clockwise and counterclockwise. It can be done easily. In addition, by printing the determination graphic B and the determination graphic E on the same sheet, it is possible to easily determine the angle between the line segment indicating the azimuth at a position away from the building and the building.
That is, the “grid lines B1a, B1b” correspond to “auxiliary lines” of the present invention, and the “scale line E1” corresponds to “determination lines” of the present invention.

The performance ruler A can be easily obtained without having to measure the dimensions on the drawing with the ruler each time because the determination figures B, C, D, and E are printed on a single sheet. Judgment can be made on various standards related to crime prevention and disaster prevention established by the Building Standards Law and the Housing Quality Assurance Promotion Law. In particular, the contents of the check by the above-described determination figures B, C, D, and E can all be performed by the performance ruler A. Therefore, it is not necessary to use a plurality of check tools, and the check work is made efficient.
Note that the arrangement of the determination figures B, C, D, and E on the performance ruler A is not limited to such an arrangement, and can be an arbitrary arrangement. Further, the combination of the scale and the reduction rate can be arbitrarily set. Further, the number of determination figures printed on the performance ruler A is not limited to these four, and any combination can be used. Further, determination figures other than the determination figures B, C, D, and E may be added. For example, not only a determination as to whether or not a certain criterion is satisfied, but also a determination figure that determines which one of the predetermined ranks belongs to may be used.

In addition, since the determination figures B, C, D, and E are configured to be able to check a reduced drawing reduced at a reduction rate of 70%, a drawing having the same size as the original drawing need not be used as a check drawing. Convenience is improved.
In addition, when the reduced scale of an original drawing is small, you may enable it to use an enlarged drawing. In short, the determination figure may be created with an arbitrary dimensional ratio according to the scale of the original drawing and the drawing size to be used as the check drawing. For example, the determination figure is created corresponding to an original drawing with a scale of 1/50 or 1/100, but may be made to correspond to an original drawing with a scale other than this.

  The performance ruler A can be created by printing judgment figures (judgment figures B, C, D, E) on the OHP sheet using printing means such as a color printer or copier. can do. Further, the performance ruler A applicable to check drawings having different reduction ratios can be easily created simply by changing the output ratio. Further, since the judgment figure can be easily corrected, the drawing check tool can be quickly corrected when the design standard is revised.

It is explanatory drawing of the determination figure (determination figure B) for determining a performance ruler A and a fire spread line. It is explanatory drawing of the determination figure (determination figure C) for determining a crime prevention division. It is explanatory drawing of the determination figure (determination figure D) for determining the position of a sensing alarm device. It is explanatory drawing of the determination figure (determination figure E) for determining an azimuth | direction and an angle.
